Learning Goal: A 1290 -kg car is pushing an out-of-gear 2200 -kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push horizontally against the ground with a force of 4580 N. The rolling friction of the car can be neglected, but the heavier truck has a rolling friction of 755 N, including the "friction" of turning the truck's drivetrain. What is the magnitude of the force the car applies to the truck?
